A man searching for the truth about his wife's killer learns more than he wanted to know about her own private story in this powerful drama. Harry Cain (John Turturro) works as a security guard at a large shopping mall in Wisconsin.
Harry's life takes a sudden and disturbing left turn when his wife, Kate (Deborah Kara Unger), is shot to death in the mall's parking facility. Devastated by his wife's passing, Harry begins combing over every scrap of evidence he can find in hopes of tracking down the gunman and reviewing hours of videotape from the mall's surveillance system.
One night, Harry has a vision in which he sees Kate walking out of the house across the street; he breaks into the abandoned home to investigate, and finds some photographs that may lead him to his wife's murderer.
However, the more Harry learns about Kate, and as he travels to Montana in search of a possible culprit, Harry begins to learn just how much he never knew about Kate and her life. Renowned novelist Hubert Selby Jr. co-wrote the screenplay for Fear X, while composer and musician Brian Eno contributed to the musical score.
